DETAILED DESCRIPTION OF NON-LIMITING EXAMPLE EMBODIMENTS

FIG. 1 is a diagram showing a configuration of display system 10. Display system 10 is a system for displaying a variety of images in accordance with operations performed by a user. Display system 10 includes controller 100, monitor 200, and main device 300.

Controller 100 is a portable display device, and also is an operation terminal via which a user performs a variety of operations. Controller 100 is provided with an operation means such as notions 161, in addition to display region 141. Controller 100 causes a variety of images to be displayed in display region 141 based on data transmitted from main device 300, and generates operation information indicating an operation state of buttons 161, and transmits the generated operation information to main device 300.

Monitor 200 is a stationary-type display device, and may be, for example, a television set for receiving a television broadcast or a display of a personal computer. It is assumed that monitor 200 has display region 201 having a larger size than display region 141 of controller 100, though display region 201 may be the same size as or smaller than display region 141 of controller 100.

Main device 300 is a computer that executes programs and serves as an information-processing device for controlling operation of controller 100 and monitor 200. Main device 300 is connected to each of controller 100 and monitor 200 via wired or wireless communication. It is assumed here that main device 300 conducts wireless communication with controller 100 and conducts wired communication with monitor 200. Main device 300 has a multitask function whereby it is capable of executing multiple application programs in parallel. In accordance with this multitask function, main device 300 executes in parallel, for example, a game program in use by a user and a browser program for allowing the user to browse web pages.

Main device 300 causes at least one of controller 100 and monitor 200 to display an image. Depending on a user operation and/or a type of an image to be displayed, main device 300 may cause only one of controller 100 and monitor 200 to display an image or may cause each of controller 100 and monitor 200 to display an image. It is to be noted that, in a case where an image is displayed on each of controller 100 and monitor 200, main device 300 may cause the same image to be displayed on controller 100 and monitor 200, or may cause different images to be displayed on controller 100 and monitor 200.

While a user is playing a game using this display system 10, if the user wishes to discover an effective way to complete the game, for example, the user may operate controller 100 to activate a browser program of main device 300. At this time, main device 300 causes monitor 200 to display a captured image (a so-called “screen shot”), which was displayed on controller 100 and monitor 200 during playing of the game immediately before activation of the browser program, and causes controller 100 to display an image of the newly activated browser program. Further, main device 300 presents to the user information relating to the game program (hereinafter referred to as application-related information), such as the title of the game being played, as a candidate for a keyword indicating an item of information to be searched for (hereinafter, referred to as a search item), together with the image of the browser program displayed on controller 100. This presentation may be achieved in any way, such as by display of an image representing the application-related information or by output of sound representing the application-related information, so long as the information is conveyed to the user. In this exemplary embodiment, explanation will be given taking display of an image as an example. When a user instructs the browser program to conduct a search using the presented application information as a search item, a search engine on the Internet or the like operates in response to a request from the browser program, and main device 300 can obtain a result of the search performed by the search engine.

FIG. 4 is a block diagram (functional block diagram) showing a principal functional configuration of main device 300. Main device 300 includes storage unit 301, acquisition unit 302, presentation unit 303, and instruction unit 304. The functions of these units are realized by execution of one or more programs by control unit 310 of main device 300. It is to be noted that main device 300 does not have to include every unit shown in FIG. 4. Further, main device 300 may realize the functions of the units shown in FIG. 4 by executing a single program or multiple programs.

Storage unit 301 is a means realized by auxiliary storage unit 320, for example, and stores application-related information, which is information relating to a first application program, in association with a type of the first application program. In a case where the type of the first application program is a game program, for example, the application-related information is the title of the game.

Acquisition unit 302 is a means realized by control unit 310, for example, and acquires the application -related information, which is information relating to the first application program. For example, in a case where the first application program is a game program and the application-related information is the title of the game, acquisition unit 302 acquires the title of the game from storage unit 301.

Presentation unit 303 is a means realized by control unit 310 and terminal communication unit 350, for example, and, when a second application program, by which a search can be performed, is activated after activation of the first application program, presents to a user the application-related information relating to the first application program and acquired by the acquisition unit, as a candidate for a search item in the search. For example, in a case where the first application program is a game program, the second application program is a browser program, and the application-related information is the title of the game, presentation unit 303 transmits to controller 100 image data representing the title of the game, for example, to cause the title to be displayed on display 140, thereby presenting to the user the title as a keyword serving as a candidate for a search item.

Instruction unit 304 is a means realized by control unit 310, for example, and, in response to an operation performed by a user for the application-related information presented by presentation unit 303, instructs the second application program to search for information relating to the application-related information. For example, in a case where the first application program is a game program, the second application program is a browser program, and the application-related information is the title of the game. Instruction unit 304 instructs the browser program to search for information relating to the title of the game. As a result of execution of the browser program in accordance with this instruction, information relating to the title of the game, such as an effective way to complete the game, is retrieved by a search engine on the Internet 400 or the like, as a search result. The obtained search result is transmitted from main device 300 to controller 100 to be displayed on display 140.

Next, explanation will be given of an operation of this exemplary Embodiment. FIGS. 5 and 8 are flowcharts showing a process performed by main device 300. Upon activation of a game program, control unit 310 of main device 300 generates game data according to a procedure described in the game program, where the game data includes image data representing game images, sound data representing the sound output while each game image is displayed, and so on (step S1). The game data includes two types of game data: game data for the controller, which is to be output from controller 100; and game data for the monitor, which is to be output from monitor 200. Control unit 310 generates the two types of game data.

Next, control unit 310 transmits the game data for the controller to controller 100 via terminal communication unit 350, and transmits the game data for the monitor to monitor 200 via AV interface 360 (step S2). Upon receipt of the game data for the controller, control unit 110 of controller 100 displays, in display region 141, a game image based on the image data, and outputs sound according to the sound data. On the other hand, upon receipt of the game data for the monitor, monitor 200 displays, in display region 201, a game image based on the image data, and outputs sound according to the sound data.

FIG. 6 is a diagram showing exemplary game images displayed on controller 100 and monitor 200. Displayed in display region 201 of monitor 200 is an image showing character C1, which is a main character in a game, and character C2, which is a monster against which the main character fights, viewed from the side in a virtual three-dimensional space. On the other hand, displayed in display region 141 of controller 100 is an image showing characters C1 and C2 viewed from above in the virtual three-dimensional space.

Referring again to FIG. 5, if a user performs an operation with controller 100 during the progress of the game (step S3; YES), control unit 110 of controller 100 generates operation information representing the operation and transmits the operation information to main device 300. Control unit 310 of main device 300 acquires the operation information from controller 100. Control unit 310 determines whether the operation represented by the operation information is an operation relating to progress of the game (step S4). If the operation is an operation relating to the progress of the game (step S4; YES), control unit 310 identities an event corresponding to the operation (step S5), and generates game data by applying the event to the procedure described in the game program (step S1). While the game is in progress, step S1 to step S5 are repeated.

If it is determined in step S4 that the operation performed by the user is not an operation relating to the progress of the game (step S4; NO), control unit 310 determines whether the operation represented by the operation information is an operation instructing return to display of a home screen (step S6). A home screen is an image displayed first to guide various functions provided by main device 300. If the operation is an operation for returning to the home screen (step S6; YES), control unit 310 temporarily suspends execution of the game program, reads out image data of home screen from auxiliary storage unit 320, and transmits the image data of home screen to controller 100 via terminal communication unit 350 and to monitor 200 via AV interface 360 (step S7). Upon receipt of the image data of home screen, each of control unit 110 of controller 100 and monitor 200 displays the home screen based on the image data of home screen.

Arranged in this home screen are, in addition to a soft key for activating a browser program, a soft key for viewing television, a soft key for displaying a so-called: help function, and a soft key for displaying various other menus, for example.

When an operation for activating a browser program is performed in the home screen (step S8; YES), control unit 310 activates the browser program (step S9). Then, control unit 310 transmits to monitor 200 game image data, which is image data for the game displayed on each of monitor 200 and controller 100 immediately before transition to the home screen (namely, immediately before temporary suspension of execution of the game program), and transmits to controller 100 browser image data representing an image of the browser program (step S10).

At this time, control unit 310 reads out the title of the game stored in association with the game program (for example, “ADVENTURES OF A PRINCE”) from auxiliary storage unit 320, and transmits the title of the game to controller 100 as a part of the browser image data. Upon receipt of the game image data, monitor 200 displays a game image based on the game image data. On the other hand, upon receipt of the browser image data, control unit 110 of controller 100 displays a browser image based on the browser image data. It is to be noted that, if the determination in steps S6 and step S8 is “NO,” control unit 310 of main device 300 performs a predetermined corresponding process (step S11). For example, if an operation instructing return to the game is performed, control unit 310 of main device 300 restarts execution of the game program from the point at which the procedure was suspended. Namely, in accordance with the procedure described in the game program, control unit 310 generates game data for controller and game data for monitor, and transmits them to controller 100 and monitor 200, respectively. As is described in the foregoing, control unit 310 serves as a return unit for restarting progress of a game caused by execution of a game program from a point at which the progress was suspended.

FIG. 7 is a diagram showing exemplary images displayed on controller 100 and monitor 200 when a browser program has been activated. Displayed in display region 201 of monitor 200 are game image g1, which was displayed in display region 201 of monitor 200 immediately before transition to the home screen, and game image g2, which was displayed in region 141 of controller 100 immediately before transition to the home screen. On the other hand, displayed in display region 141 is a browser image. In this browser image, message m ‘SEARCH FOR “ADVENTURES OF A PRINCE”’ is displayed in connection with soft key SK5 for transition to a search image, as a form of a so-called balloon superimposed on the browser image. A user recognizes this string of characters “ADVENTURES OF A PRINCE” as a candidate for a search item. As is described in the foregoing, when a browser program is activated, in place of an image displayed as a result of execution of a game program, an image displayed as a result of execution of the browser program and message m including application-related information such as ‘SEARCH FOR “ADVENTURES OF A PRINCE”’ are displayed in display region 141 of controller 100.

Next, with reference to FIG. 8, if the user performs an operation with controller 100 (step S12; YES), control unit 310 acquires operation information from controller 100, and determines an operation content (event) of the operation information (step S13). If the operation content (event) is touching, by the user, of message m displayed as a balloon (step S13; touch search item), control unit 310 determines that an operation instructing a search for the string of characters “ADVENTURES OF A PRINCE” included in message m is performed, and performs a search with “ADVENTURES OF A PRINCE” being a search item (step S17). Namely, in this process, control unit 310 notifies the browser program of an event corresponding to an operation performed by a user, to perform a process for searching in accordance with a procedure described in the browser program, while maintaining au image displayed as a result of execution of a game program to be displayed on monitor 200.

Subsequently, when a result of the search is obtained, control unit 310 transmits to controller 100 search result image data representing the search result (step S18). Upon receipt of the search result image data, control unit 110 of controller 100 displays a search result image based on the received search result image data. Thus, even when an image for inputting a search item is not displayed as a result of activation of a browser program, the browser program is given an instruction to search for information relating to the string of characters “ADVENTURES OF A PRINCE” included in message m.

FIG. 9 is a diagram showing an exemplary search result image displayed on controller 100. In a search result image displayed in display region 141 of controller 100, below the string of characters “ADVENTURES OF A PRINCE,” which is the search item, results of the search for information on the Internet 400 relating to the string of characters are displayed. A user can select a desired result from the displayed search results to browse the information in detail.

Referring again to FIG. 8, in step S13, if the operation content (event) is touching, by a user, of soft key SK5 for transition to a search image (step S13; touch soft key for search), control unit 310 transmits to controller 100 search image data representing a search image (step S14). At this time, control unit 310 reads out from auxiliary storage unit 320 the title of the game “ADVENTURES OF A PRINCE” stored in association with the game program, and transmits the title of the game to controller 100 as a part of the search image data. Upon receipt of the search image data, control unit 110 of controller 100 displays a search image based on the search image data.

FIG. 10 is a diagram showing an exemplary search image displayed on controller 100. In a search image displayed in display region 141 of controller 100, the string of characters “ADVENTURES OF A PRINCE” is inputted automatically (i.e., without need for an input operation performed by a user) and displayed in input field A for inputting a search item. Below input field A are displayed soft keys SK7 resembling a keyboard. As is described in the foregoing, when message m including the string of characters “ADVENTURES OF A PRINCE” shown in FIG. 7 is selected (step S13; touch search item), a search for the string of characters “ADVENTURES OF A PRINCE” is performed immediately, and, on the other hand, when soft key SK5, which is an operation element indicating search, is selected (step S13; touch soft key for search), the screen image is caused to transition to a search image in which the presented string of characters “ADVENTURES OF A PRINCE” has been input as an initial value.

By using soft keys SK7, the user can input desired characters into the input field in addition to the string of characters “ADVENTURES OF A PRINCE.” For example, if the user wishes to know options for attacking the monster displayed on monitor 200, the user may input one or more strings of characters such as “dinosaur,” “monster exhaling fire,” or “attack,” in addition to the string of characters “ADVENTURES OF A PRINCE.” At this time, the game image shown on monitor 200 (FIG. 7) may be viewed as reference or ‘help’ information when the user inputs a keyword(s) serving as a search item(s).

Referring again to FIG. 8, since the string of characters “ADVENTURES OF A PRINCE” has been input automatically in the input field for inputting a search item, as described with reference to FIG. 10 (step S15; YES), upon touching, by the user, of soft key SK6 for instructing a search, control unit 310 receives operation information corresponding thereto (step S16), and performs a search in accordance with the search instruction (step S17). When a result of the search is obtained, control unit 310 transmits to controller 100 search result image data representing the search result (step S18). Upon receipt of the search result image data, control unit 110 of controller 100 displays a search result image based on the search result image data (refer to FIG. 9). Thus, irrespective of whether a search image for inputting a search item is displayed as a result of activation of a browser program, it is possible to instruct the browser program to search for information relating to the string of characters “ADVENTURES OF A PRINCE.”

Further, in a case where it is determined in step S13 that the operation content (event) is touching, by the user, of an area other than soil key SK5 and message m (step S13; touch another part), control unit 310 transmits browser image data to controller 100. Upon receipt of the browser image data, control unit 110 of controller 100 displays a browser image based on the image data (step S19).

FIG. 11 is a diagram showing an exemplary browser image displayed on controller 100. In a state where a browser image is displayed on controller 100, message m ‘SEARCH FOR “ADVENTURES OF A PRINCE”’ is not displayed in connection with soft key SK5 for transition to a search image. Namely, when compared to FIG. 7, the browser image is displayed with message m being deleted. In this image, when soft key SK5 for transition to a search image is touched (step S20; YES), control unit 310 transmits to controller 100 search image data representing a search image (step S14). At this time, control unit 310 reads out from auxiliary storage unit 320 the title of the game “ADVENTURES OF A PRINCE” stored in association with the game program, and transmits the title of the game to controller 100 as a part of the search image data. As a result, an image identical to that shown in FIG. 10 is displayed on controller 100. Namely, deleted message m is presented again as a search item. By using soft keys SK7, the user can input desired characters into the input field in addition to the string of characters “ADVENTURES OF A PRINCE.”

Modifications

The exemplary embodiment described in the foregoing is one embodiment for carrying out the exemplary embodiment. The exemplary embodiment is not limited to the exemplary embodiment, and can be carried out in other embodiments, as shown by the following modifications. It is to be noted, that multiple modifications may be combined in carrying out the exemplary embodiment.

Modification 1

In the exemplary embodiment, a game program is described as an example of a first application program, and a browser program is described as an example of a second application program. However, the first application program and the second application program are not limited to the examples described in the exemplary embodiment. The first application program may be any program, and the second application program may be any program that can perform a search. The second application program may be, for example, an application program, such as dictionary software, which pre-stores information and performs a search for information according to a request input by a user. Namely, the search process performed by the second application program may be a search process performed via the Internet 400, or it may be a search process performed by accessing a storage device without accessing the Internet 400.

Modification 2

Display device 10 may be used without use of monitor 200. Though an image is displayed on each of controller 100 and monitor 200 in the exemplary embodiment, it is possible to display an image only on controller 100 or only on monitor 200. In this case, control unit 310 of main device 300 causes a game image of a first application program (e.g., game program) to be displayed on either controller 100 or monitor 200, and, when a second application (e.g., a browser program) is activated, causes a browser program to be displayed in place of the game image. Further, control unit 310 of main device 300 may display an image displayed by execution of a first application program (e.g., game program) and an image of a second application program (e.g., browser program) via which a search can be performed, simultaneously on a single display device, by dividing the display region of the display device into multiple parts, for example.

Modification 3

In the exemplary embodiment, application-related information relating to a first application program is stored in storage unit 301 in association with a type of the first application program. The stored application-related information is not limited to the title of a game, and may be any information so long as it relates to the first application program.

Further, it is also possible to store application-related information relating to the first application program in storage unit 301 in association with a state of execution of the first application program when the first application program is executed. A state of execution here indicates a variable procedure executed in the program. For example, in a case where the first application program is a game program, it is possible that, for each image displayed in the game, a string of characters representing the content of the image is stored as the application-related information. Further, for each scone in the game, a string of characters representing the scene may be stored as the application-related information. At this time, in a case where the game presented by the first application program is a game played in a virtual three-dimensional space, for example, a point of view and a viewing direction perceived by a user when viewing the virtual three-dimensional space may vary in accordance with an operation performed by the user, and this may result in a possibility of various game images displayed for the same scene in the game. Therefore, in this case, it can be said that the application-related information is stored for each scene of the game, rather than that the application-related information is stored for each image displayed in the game.

Modification 4

In the foregoing exemplary embodiment, when a browser program is activated while the user is playing a game using display system 10, control unit 301 of main device 300 causes monitor 200 to display a captured image (so-called “screen shot”), which was displayed on controller 100 and monitor 200 during playing of the game immediately before activation of the browser program.

The image displayed on monitor 200 at this time is not limited to the image that was displayed on controller 100 and monitor 200 immediately before activation of the browser program (second application program). For example, in a case where multiple game scenes are provided by execution of the game program (first application program), a single image for each game scene may be set as a screen shot. In this case, control unit 301 may cause the image set for the game scene at the time the browser program (second application program) is activated to be displayed.

Further, the image displayed on monitor 200 at this time is not limited to a stationary image as a screen shot, and may be a moving image. For example, control unit 301 may cause a moving image displayed on controller 100 or monitor 200, in accordance with execution of a game program (first application program) during a predetermined period before activation of a browser program (second application program), to be displayed on monitor 200.

Modification 5

The exemplary embodiment does not have to be carried out in a main device 300, in a display system including main device 300 and controller 100, or in a display system (display system 10) further including monitor 200, but also can be carried out in an information-processing device including integrally a configuration corresponding to main device 300 and a configuration corresponding to controller 100.
